Additionally, for a testing framework to poke signals through the

for exercising floppy drives on a sub-system-by-subsystem basis?

You should check out a couple of disk utility programs for the Model 4:
Super Utility 4/4P
http://tim-mann.org/trs80/su4a.zip (CMD version)
https://fjkraan.home.xs4all.nl/comp/trs80-4p/dmkeilImages/util/97-0005.ace
(bootable version)
http://tim-mann.org/trs80/doc/su4man.pdf
Hyperzap 3.2C
https://fjkraan.home.xs4all.nl/97-0002.ace
If you hook up a working drive to boot from, one of those should help
to exercise/exorcise the bad drive. :-)
